To all 717101 it vm/fz/y/ eowern:

Be it known that I, HENRY E. HUBBELL, a citizen of the United States, residing at Johnson, in the county of Lamoille and State of Vermont, have made certain new and useful Improvements in Bookcases, of which the following' is a specification.

My invention is an improvement in cases adapted for holding' books or merchandise or the like; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a sectional elevation of a case embodying my invention. Fig'. Q is a cross-section on about line Q 2 of Fig'. 1, and Fig. 3 is a detail perspective view showing a portion of the upright and one of the bearings thereon for the shelves.

In carrying' out my invention I provide a base A, on which is mounted the uprightor standard B, made of suitable length to extend through the main frame of the case and to support the same at its upper end. The main frame of the case comprises, as shown, a bottom plate O, a top plate D, and connections E between said plates C and I). 'Ihcse connectiens may preferably be in lthe form of rods, as shown. The upper plate D is provided at its center with a bearing' D', restingl on the upper end of the upright B, and the bottom plate O is supported on ball-bearings O from the base A, so the main frame can be readily revolved when desired. Shelves F are supported on the shaft B and are preferably arranged for adjustment up and down, so they may be set to different positions relatively. I prefer to adjust the shelves independently and to secure this adjustment by the means shown, which lincludes supports (jr, encircling and movable longitudinally along' the upright B and having means for securingthem in suitable adjustment. This is shown as comprising ratchet-teeth B in the upright B and pawls G', carried by the shelfsupports (r and engaging with the ratchets B to hold the shelves in different adjustments. By this means the shelves may be adjusted up and down independently and may be supported in any desired position. In their upper ends the supports are provided with races for balls g, so the shelves are support ed by ball-bearings to facilitate their ready turning' in the use of the invention. It will thus be noticed I provide a main frame which can be revolved about the central upright and also shelves which can be revolved independently of each other and of the main frame upon the central upright and can be adjusted up and down along the upright and held in any suitable position.

In connection with the shelves and the main frame I provide a door, which preferably consists of two semicylindrical sections H and I, the latter being slightly smaller than the former and arranged to turn therein when desired. These doors revolve within circular ianges D`l and C, projecting', respectively, from the under and upper sides of the plates D and O and excluding' from view and protecting the opposite ends of thc door-sections. The door-sections, which may be provided with curved plates of glass to expose the contents of the case or may be constructed of other suitable material, as desired, are supported by arms H and I, connected at their outer ends with their respective door-sections and having at their inner ends bearing portions mounted on ball-bearings. As shown, balls J are arranged in a suitable race J' below the bearing I at the inner end of the arm I', and the upper side of said bearing' Ii is provided with a ball-race receiving' balls, upon which rests the bearingl H at the inner end of the arm H. This describes the construction for supporting the inner ends of the upper arms I-I and H2. The inner ends of the lower arms supporting' the door-section are similarly constructed, it beingunderstood that the door-supporting arms are provided at their inner ends with bearing-rings fitting' around the upright B, one above the other, balls being interposed between the said bearings and below the lower one of the said bearings in both the upper and lower construction for supporting' the door-sections.

Having' thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The improvement in bookcases herein described, comprising' the base, the upright thereon, the main frame having a top plate resting on the upper end of the upright, and a lower plate connected with the top plate, ball-bearings below the bottom plate, the shelves encircling thc upright and adjustable longitudinally along' the same, supports below the shelves and provided with ball-races and balls therein supporting their respective shelves, means for securing' these supports in different positions along' the upright, doorsections operating between the upper and lower plates of the main frame, arms con- IOO IIO

revolved thereon and for adjustment longitudinally along the uprightV to different positions, and means for supporting the shelves in Y any suitable adjustment longitudinally along the upright, substantially as set forth.

3. v The combination substantially as herein described, with the upright and shelves supported thereon, of the door-sections, arms connected at their outer ends with said seotions and provided at their inner ends with bearing rings encircling the upright, one above the other, balls between the upper and lower bearing-rings, and the support below the lower ring and balls between said support and such ring, substantially as set. forth.

4L. The combination with an upright having ratchet-teeth and a shelf movable along the upright and adapted to revolve thereon, of a support below the sheltI and a pawl carried by the support and engaging the ratchet-teeth of the upright, substantiallyas set forth.

HENRY E. HUBBELL.
